Method and device for avoiding robot collision

Abstract

The invention discloses a method and device for avoiding robot collision, and relates to the technical field of computers. One embodiment of the method comprises the steps of generating a datum pointset from a start point to a target point through path planning, and acquiring interference area identities corresponding to datum points of the datum point set; splitting the datum point set accordingto the interference area identities corresponding to the datum points, and setting interference area identities for multiple child routes obtained through split respectively; and locking the corresponding interference areas according to the interference area identities of the child routes, and issuing route instructions after locking succeeds to enable the robot to enter an interference area, wherein the interference area is acquired by dividing the datum points according to distribution of the datum points in a target area. According to the method for avoiding robot collision, because the interference area is marked off beforehand, and the interference area identities are set for the child routes, the corresponding interference area is locked according to the interference area identitiesof the child routes, it is guaranteed that only one robot can enter the interference area, and robot collision is avoided.

Description

technical field [0001] The invention relates to the field of computers, in particular to a method and device for preventing robot collisions. Background technique [0002] After receiving the task sent by the upstream system, the robot control system will perform path planning to obtain the reference point set passed from the starting point to the target point; the reference point set is sent to the robot, and each reference point set of the reference point set The point is set with a reference point number, and the robot analyzes the reference point number to obtain the position information of the corresponding reference point, and then moves to the target point along the trajectory corresponding to the reference point set. Wherein, the robot is, for example, a transportation robot (unmanned forklift), a sweeping robot, and the like. [0003] When there are more than one robot in the target area, the anti-collision effect between the robots will have a great impact on whet...

AI Technical Summary

Problems solved by technology

[0005] (1) The anti-collision mechanism at the hardware level relies on the detector. For the situation where the detector cannot detect the surrounding robots in time, such as a robot driving in the opposite direction at an intersection, the detector cannot detect the opposing robot in time, resulting in a sudden collision stop;

[0006] (2) The anti-collision mechanism at the software level requires locking and releasing each reference point that the robot walks, which will cause the robot to drive slowly and affect the efficiency of task execution; Entering multiple robots prevents the robot that entered first from being able to back out
